(1) We use 'Copinger' rather than 'Coppinger' for the file name because that appears to be spelling used by the main branch of the family for many years. It appears that the spelling with two Ps was used mainly by the branch that settled in Ireland.
(2) WAC reports of tthe following John that "The Copingers had long previously flourished in Buxhall" and "The family was in immediate connection with a branch of the Copingers in the county of Cork, Ireland. In the time of John Copinger's father some of the family had passed into Ireland". Commoners (vol 2, 'Coppinger of Ballyvolane', p326) reports "So far back as the beginning of the fourteenth century (anno 1319) we find, by the municipal records of Cork, Stephen Coppinger, mayor of that city". We presume to show Stephen, Mayor of Cork, as an uncle of John's father but stress that we do not know exactly how the branches were connected.
